REGISTER.

Specification of Letters Patent.

Application filed March 31,

Patented June 22, 1909. 1908. Serial No. 424,435.

. of which the following "is a specification.

This invention relates to registers and comprises essentially a disk mounted to turn in a casing and provided with a series of numbers around the edge thereof, any one of which may be exposed through the casing, and an operating device is provided which may be worked by hand to advance the disk, a feature of the device being that the disk can be turned either one or two numbers at each operation, as selected. A release device allows the disk to turn back to zero.

The invention will be found particularly useful for accountants, who may desire to keep account of 10s or 20s in adding a long column of figures, but may be used whenever it is necessary to keep a register or account of numbers or articles.

The invention is illustrated in the accompanying drawings, in which,

1 Figure 1 is a front view of the'device. Fig. 2 is a lan of the disk. -Fig. 3 is a front view, with t e front of the casing removed. Fig. 4 is a section on the line 44 of Fig. 1.

Referring specifically to the drawings, 6 indicates a circular casing which may be made somewhat similar to a watch case and provided with a stem 7 at one side whereby it can be readily held between the fingers. \Vithin the casing is a rotary disk 8 mounted at the center upon a 1pivot pin 9 supported on the casing. This dis has a series of numbers 10 extending around the front edge thereof in position to be explosed through an opening 11 in the front of t e case. The disk is fastened to a ratchet wheel 12 having teeth corresponding in number and position to the numbers on the disk. The disk is turned by means to be described, in resistance to the spring 13 coiled around the axis 9, and when released turns back to zero and is there stopped by means of a pin 14 which strikes against a lug 15 projecting from the back of the casing.

16 and 17 are two operating levers or devices which are fulcrumed at their inner ends on the ivot 9 and which extend respectively throug slots 18 and 19 in the, rim of thecaslatter being supported by a spring 26.

tail of the ing. The slot 19 is longer than the slot 18 The lever 17 carries a pawl 20 engageable with the teeth of the ratchet, and has an offsetportion 21 which rests against the lever 16 when the parts are in normal position. A

spring connected to the lever 17 and acts to return the same to normal position after each operation. 20 extends between a The tail of the pawl rearwardly as at 23, to position detent 24 and a push pin 25, the The detent 24 serves to normally engage the ratchet and prevent back slip thereof.

The disk is turned by movement of one of the levers 16 or 17. When the lever 16 is moved to the right it carries with it the lever 17 which carries the pawl 20 and causes the same to "urn the ratchet accordingly; or the lever 17 may be moved to'the right, alone, causing the ratchet to turn accordingly. The slots 18 and 19 are of such length as to permit the movement of the lever 16 to the right to move the ratchet wheel one tooth, and the movement 'of the lever 17 to the right to move the ratchet wheel two teeth. In either event the spring 22 returns the levers to original position as soon as they are released. When the push pin 25 is pressed in it strikes the tail of the pawl 20 and releases the same, which also presses on the detent 24 and disengages the same, allowing the ratchet wheel and disk to turn back to zero. When the push. pin is released the pawl and detent again engage, each being provided with a spring for that purpose, and the device is then ready for the next operation. In adding a column of figures, for example, the addition may proceed mentally, and as each l0 is counted the lever 16 is moved, thereby turning the disk one space, which will register the number of 10s contained in the column. When a column iscounted by 20s the lever 17 is manipulated in the same way, which will move the disk two spaces at each operation and thus show the number of 10s contained in the column.

The invention is not limited to the exact form shown and described, since obviously various modifications may be made in the mechanical structure within the scope and principle of the invention.

I claim:

A register comprising a casing, a numbered disk rotatable therein and having a ratchet the rear lever to less distance than that of wheel with teeth corresponding to the numbers, levers'mounted to swin beside the Wheel, one lever being locaterrbehind the other, the front lever having a pawl thereon engaging the ratchet and normally resting against the rear lever so as to move therewith, and means to limit the movement of the front lever 10 In testimony whereof I ailiX my signature, 'in presence of two witnesses.
